7 Claims.

This invention relates to a power operated machine for washing and antiseptically cleaning drinking glasses and other like containers by a solution of water and an admixture of a measured quantity of a chemical antiseptic cleansing fluid in combination with revolving brushes and water sprays.

An object of my invention is to speed the operation of washing and cleansing of tumblers where the same are used in large quantities.

A further object of my invention is to provide quick and convenient means for the antiseptic cleansing of tumblers by providing a mechanism that automatically dispenses a measured quantity of antiseptic cleansing fluid to the water passing through the machine for cleansing purposes.

A still further object of my invention is to provide a machine that will operate in conjunction with all hydrostatic pressures and may be automatically operated by simply applying the glasses or tumblers to the brushes.

Still another object has been to simplify the construction and mechanism of machines of this character whereby the costs of same are greatly reduced and economies of operation are effected.

A particular object of my invention has been to provide a machine of this character that will operate as successfully with glasses of light and fragile construction as with glasses of heavier mould without breakage.

A final object of my invention has been to eliminate the necessity of using any dangerous pressure of force to the glasses in applying them to the brushes to either start the machine or brushes or water sprays, thereby making it possible for a child to operate the machine if desired.

My invention consists essentially of the construction and arrangement of parts more specifi- 0 cally pointed out and described in the following specification and further illustrated in the accompanying drawings forming part of this application and in which:

Figure 1 is a perspective view of the washing machine positioned below the drain board and shows the washing bowl and motor driving the machine.

Figure 2 is a detail View of the quick break switch shown covered in Figure 1 and mounted upon the side of the machine and connected to the electric motor through the panel box on the motor stand.

Figure 3 is a perspective view of the drain board and shows washing bowl and revolving brushes and top of the control rod.

Figure 4 is a sectional elevation of the main body of the machine and shows antiseptic chamber and inflation receptacle therein, also washing solution chamber with pivoted lever mounted therein with mixing chamber and washing bowl with revolving brushes mounted upon the top of washing solution chamber.

In these drawings like parts are represented by like numerals and in Figure l the numeral 1 indicates a metal bowl having the drain pipe 2 connected therewith, while 3 indicates its sup ports. Through the bottom of the' bowl 1 there extends a hollow shaft 4 on which is mounted the grooved pulley 5 driven by the belt 6 from the motor '7. The motor is mounted on a suitable stand 8 on the side of which is secured the panel box 9 containing the wiring connections of the motor.

The hollow shaft 4 is carried in the bearing 10 mounted upon the cover plate 11 of a washing solution chamber 12, which chamber is in turn mounted upon an antiseptic chamber 13 forming the lower part of the machine. The whole machine is mounted upon the base 14 comprising the support.

A water supply pipe is indicated at 15 traversing the back of the machine and being connected into the upright pipe 16, the lower end of which is connected into the bottom of the antiseptic chamber 13 through the T 1'7, the outer branch of which is connected into the drain pipe 18 having the valve 19 positioned in it.

The upper part of the pipe 16 is connected through the coupling 20 into the mixing chamber 21, the opposite side of which is connected to the antiseptic chamber 13 by the pipe 22 having the valve 23 in the line. The pipe line 22 is connected into the antiseptic chamber 13 through the horizontal sight feed glass 24 by which the flow of the antiseptic fluid may be observed.

Positioned upon the side of the washing solution chamber 12 is a switch box 25 containing a quick break switch 26 (not shown in Figure 1), controlling the motor '7. The switch 26 is connected to the panel box 9 by the lead 27.

An enlarged View of the switch 26 is shown in Figure 2 and it is operated by the switch arm 28 mounted upon the rod 29 extending through the side of the washing solution chamber 12, which bearing is in turn connected to a pivoted lever arm 36 mounted in the washing solution chamber shown in the sectional elevation Figure 4.

In Figure 3 is shown a perspective view of the drain board of the washing machine showing the partly covered top of the bowl 31 containing the revolving brushes 30 in the, centre of which is shown the extending top of the control rod 31 by which the machine is operated.

In Figure 4 the antiseptic chamber is shown at 13 containing an inflation receptacle 32 connected to the upright water supply pipe 16 through the T 17. On the top of the receptacle 32 is a plate 33 serving both to depress the inflation receptacle when being emptied and as a support to a pair of plunger arms 34 positioned upon each side of the antiseptic chamber 13, one of the arms serving as a gauge to indicate the amount of fluid in the chamber 13 and being positioned within an open faced gauge glass holder 35 located upon the flanged base of the washing solution chamber 12 and between the switch box 25 and the horizontal sight feed glass 24 (see Figure 1) while the opposite arm is positioned in an enclosed tube and merely acts as a balance member to the plunger arm used as an indicator. Both the plunger arms operate in closed tubes and compress a certain amount of air in the top of the tubes that tends to keep the plunger and the plate 33 in a level position upon the top of the inflation receptacle 3 2.

The washing solution chamber 12 is set upon 'he antiseptic chamber 13 and has mounted upon the underside of the cover 11 a lever arm 36 having one end upturned at 37 for the purpose of contacting and displacing a ball valve 38 positioned within the mixing chamber 21 and having a seat 39 formed in the cover 11.

The lever arm is pivoted in the bracket 40 secured to the underside of the cover 11 and the opposite end of the lever is secured to a control rod 31 positioned within the hollow shaft 4 and extending upwards through the centre column of the perforated brush holder 41 mounted upon the top or" the hollow shaft 4 and inside of the metal bowl 1. The revolving brushes 30 are secured to the brush holder 41. A spring 42 is attached to the end of the lever arm 36 to retain the lever in a closed position.

The hollow shaft 4 is carried in the bearing 10 mounted upon the cover plate 11 and has its lower end open to the washing solution chamber 12.

Connected to the end of the lever arm 36 immediately below its connection to the control rod 31 is the switch lever 43 connected to the bearing 29 extending through the side of the washing solution chamber 12 and being connected to the switch arm 28 operating the switch 26 (see Figures 1 and 2).

Between the valve 23 and the mixing chamber 21 is placed the restricted nozzle 44 admitting the antiseptic fluid to the mixing chamber. The nozzle 44 is secured in place by the coupling 45 and various sized nozzles may be used toproportion the antiseptic fluid to the water flow.

A filling plug, not shown, is provided for the antiseptic chamber 13.

In operation the machine is set up and connected to a water supply, the antiseptic fluid chamber 13 is filled with fluid while the inflation receptacle 32 is collapsed.

After filling the antiseptic chamber 13 the water supply is turned on through the pipe 15 and the water immediately fills the mixing chamber 21 and the inflation receptacle 32 until a pressure is set up upon the antiseptic fluid in the chamber 13 equal to the water pressure in the supply pipe 15 which forces the antiseptic fluid out through the pipe line 22 up to the valve 23 which is now opened and the antiseptic fluid in the pipe 22 meets the water pressure from the mixing chamber 21, the pressures being equal.

If a glass is now applied upon the brushes 30, see FIgure l, and the control rod 31 depressed, it immediately acts upon the pivoted lever arm 36 and displaces the ball valve 38 from its seat 39 and a water flow is set up through the mixing chamber 21 from the pipe line 22 containing the antiseptic solution and the water supply line 15 and 16. This water flow being mixed with the antiseptic fluid comprises the washing solution and fills the washing solution chamber and is forced up through the hollow shaft 4 and through the perforated brush holder 41 into a series of water sprays.

Coincident with the depressing of the control rod 31 the interconnected lever arm 36 has acted upon the switch lever 43 mounted upon the bearing 29 extending through the side of the washing solution chamber 12 and this has served to act upon the switch arm 28 connected to the motor switch 26 and has started the motor 7 and the brushes 30 revolving.

Immediately the glass is removed from the control rod 31 the lever arm 36 is raised under the action of the spring 42 (and also under the action of the hydrostatic pressure acting upon the ball valve 38 forcing it to its seat and acting upon the upturned end 37 of the lever arm 36), thereby shutting 011 the flow from the mixing chamber 21 to the washing solution chamber 12 and to the revolving brushes 30 and stopping the machine through the switch 26 being interconnected with movement of the control rod 31. Thus every time the control 31 is depressed it serves to start the motor '7 and the brushes 30 revolving, and also the water sprays through the perforated brush holder 41, at the same time the washing solution is mixed and proportioned through the mixing chamber 21.

Immediately the machine is stopped so is the Water flow therethrough, and the washing solution chamber and the revolving mechanism connected therewith are relieved of all hydrostatic pressures through the closing of the ball valve 38 in the mixing chamber 21.
